This packet contains exit tickets for the Kindergarten, Cluster 4 geometry standards. Exit tickets are written responses to questions posed at the end of a lesson. They are brief assessments which allow the teacher to determine student understanding of the concepts and skills taught that day. At the Kindergarten level, a blank copy of the exit ticket should be displayed on the board and read aloud to students. As teacher reads, students work independently on their own copy of the exit ticket.
